Si photodiodes with preamp
S9295 series
Large area photodiode integrated with op amp
and TE-cooler
The S9295 series is a thermoelectrically cooled Si photodiode with preamp developed for low-light-level detection. A large
area photodiode, op amp, TE-cooler and feedback resistor (10 GΩ) are integrated into a single package. A thermistor is also
included in the same package for temperature control so that the photodiode and I-V conversion circuit can be cooled for
stable operation. The S9295 series also features low noise and low NEP, and is especially suitable for NOx detection. The
photosensitive area of the photodiode is internally connected to the GND terminal making it highly resistant to EMC noise.
